ABC The Lissajous Curve Thingy 15+ underwent a major re-branding, changing its name to L.J. 15+ and a new look was introduced in September 2017. Later in November, the channel closed to make more room for L.J. Kids, that later began on 1 December.

The logo was created by ZombiethekidRUS on 7 October 2017 and it was known as "ABC The Lissajous Curve Thingy Kids". It was only a pre-launch campaign before it was renamed L.J. Kids for a reveal on 23 October.

Both L.J. Comedy & L.J. Kids logos were created by ZombiethekidRUS on 7 October 2017 and were revealed on 23 October. The channel is aimed at 0-15 year old children and was launched on 1 December 2017. It will not be getting its new logo alongside L.J. Comedy. Due to third-party copyright on 21 September 2018, the channel (then his most popular) got terminated.
